Drayano's hacks are pretty much the best if you're after completing the Pokédex or like the idea of cranking the difficulty.
I personally played Omicron and thought it was fun as hell, not sure how people here thought about it. I never see them talked about. But that was one of the best hacks I've ever played simply because of the fucking stupid amount of shit to plow through, and the fakemon forms are either passable enough to be enjoyable or downright hilarious. It's goofy, but I had a great time playing it.
Crystal Clear is a meme. I tried Prism and it wasn't for me, but I see sensible praise for it often.
